▎ 摘  要

NOVELTY - A flame retardant fiber comprises 40-90 pts. wt. polyethylene glycol terephthalate and 3-12 pts. wt. flame retardant. The flame retardant comprises 1-6 pts. wt. zinc borate, 1-5 pts. wt. phytic acid aqueous solution, 0.1-0.5 pt. wt. neopentyl glycol and 0.1-0.5 pt. wt. urea. USE - Flame retardant fiber. ADVANTAGE - The fiber improves flame retardant property and ensures fiber strength. The fabric prepared by fiber has good flame retardant property, limit oxygen index reaching to 37.5-41.9% and high breaking strength reaching to 806.0- 885.2 N. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing flame retardant fiber comprising mixing and smelting polyethylene glycol terephthalate and flame retardant and drawing and forming.
